Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to helmets that motorcycle drivers, construction site workers, etc. are legally obligated to wear to protect their heads, and is particularly applicable to helmets between users. This helmet is equipped with a simple radio that allows for conversation and business communications.

[Conventional technology]

Some conventional helmets carry a radio for head protection and for business communications, etc.
The transceiver is attached to a part of the body other than the helmet, such as the pocket or waist. The portable radio is a press-to-talk system, and one hand is used to operate the radio during communication.

In other words, conventional helmets that provide head protection and business communication have a headphone attached to the earmuffs of the helmet body, a microphone attached to the helmet body using a support member so as to be near the user's mouth, and a radio device attached to the body. It was attached to a portion of the radio, and one hand was used to operate the radio during communication.

[Problem that the invention attempts to solve]

However, in the case of the above conventional example, one hand is used to operate the radio, so it can only be used at construction sites etc. when transporting cargo and one's own safety will not be affected. Not only can it not be used when necessary, such as when using both hands to drive a motorcycle to ensure safety, but it can also be used at noisy airports, machine shops, subways, construction sites, and other construction sites where noise can be easily input and conversations are difficult. The problem was that it was difficult to do. Additionally, only certain people can operate it, and there is the troublesome problem of having to attach the radio to a part of the body.

[Means for solving problems]

In order to solve the above-mentioned problems, the helmet of the present invention has a jaw part of the helmet body 1 that protrudes as shown in FIGS. A microphone 3 is provided internally, a headphone 5 is provided in the earmuff 4, and other parts of the helmet body 1 are provided with:
The configuration is such that a radio device 6 is installed which uses an FM modulation method and has a tone squelch function that is voice controlled by a voice switch.

[Effect]

A microphone 3 is installed in a protrusion 2 that is an extension of the jaw of the helmet body 1, and when the user speaks the code code and voice into the microphone 3, the voice switch activates the radio 6. The transmitting unit operates and transmits the code, and the receiving unit of the communication partner receives and demodulates the modulated sound containing the code. When the code is detected, the tone squelch switch 15 operates and transmits the demodulated sound to the other party. It can be transmitted to the headphone 5 and communication can be performed. Also, if you change the encryption code, you can communicate with the other party using that encryption code. That is, by changing the encryption code, it is possible to select a communication partner and communicate with the desired partner without any operations.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

Figures 1a and 1b are a side view and a partial side view, respectively, showing an embodiment of the helmet of the present invention in which a radio device is installed at the back of the head.

In FIG. 1, reference numeral 1 denotes a helmet body, which consists of a reinforcing exterior material 11 and a cushion interior material 12 (see FIG. 3). Reference numeral 2 denotes a protruding portion formed by protruding the jaw, and a microphone 3 having directivity for capturing the user's voice is installed inside this protruding portion 2.
In this way, the microphone 3 is provided in the protruding part 2 of the jaw of the helmet body 1 and faces the user's own mouth, so it is possible to distinguish between the voice of the voice switch and the surrounding voice, and to reduce noise. Not easily affected.

In the case of this embodiment, the headphone 5 is provided on both earmuffs 4, but the headphone 5 may be provided only on one earmuff 4. In this case, the other ear can be used to absorb some external sounds. Since it can be heard, it can contribute to safety.

Other parts of the helmet body 1, in the case of the embodiments shown in FIGS.
A radio device 6 (see FIG. 2) that uses FM modulation and has a tone squelch function is provided. Figure 1a
1B shows a case where the back of the head is expanded rearward and the radio device 6 is housed within this expanded portion, and FIG. In either case, the strength required to protect the user's head is comparable to that of conventional helmets.

8 and 9 are the microphone connection parts 13 of the radio device 6, respectively.
and a lead wire or cable for connecting the horn connection section 14 to the microphone 3 and the headphone 5;
0 is the antenna.

The radio device 6 uses an FM modulation method and has a tone squelch function, and is designed to reduce frequency allocation. 15 is a tone squelch switch. In addition, rather than using high-power transmission to allow unlicensed communication, the transmission power is kept to a level that allows communication within a 100m radius.

In this invention, the installation position of the radio device 6 is shown in Figure 3 a and b.
As shown, the position may be on the top of the head of the helmet body 1. Figure 3 a shows the upper surface of the head expanded upward;
When the radio device 6 is housed in this extended portion, FIG. 3b shows the case where the radio device 6 is attached to the upper surface of the head with a holder 7.

In the helmet of the present invention having the above configuration, the radio device 6 is provided on the back of the head of the helmet body 1 or on the extended portion thereof, or on the upper surface of the head or on the extended portion thereof, so there is no risk of interfering with the protection of the user's head. , can achieve the purpose of head protection.

In addition, a microphone 3 is installed in a protrusion 2 that is an extension of the jaw of the helmet body 1, and when the user utters the code code and voice into the microphone 3, the wireless device is activated by the voice switch. The transmitting unit 6 operates to transmit the code, and the receiving unit of the communicating party receives and demodulates the modulated sound containing the code. When the code is sensed, the tone squelch switch 15 operates and transmits the demodulated sound. You can communicate with the other party's headphone 5. Also, if you change the encryption code, you can communicate with the other party using that encryption code. That is, by changing the encryption code, it is possible to select a communication partner and communicate with the desired partner without any operations. In other words, there is no need to change the frequency and search for a communication partner, and communication can be performed with a desired party by simply changing the encryption code by voice without any operation.

The microphone 3 is housed in the chin protruding part 2 of the helmet body 1 and has the directivity to capture the user's voice, so it not only protects the user's mouth but also protects the user's voice while using the encryption code. Interference from surrounding noise can be avoided, and a helmet suitable for use by motorcycle drivers, personnel at noisy airports, site workers at iron factories, subway construction, etc. can be provided.

Of course, the power source for the radio 6 installed in the helmet body 1 is a battery, and only the battery is replaceable. Although the transmission output is kept low, long-distance communication is possible if a repeater device is provided.

[Effect of idea]

As is clear from the above explanation, the present invention not only protects the user's head, but also uses the radio 6 which is voice-controlled by a voice switch and has an FM modulation system and a tone squelch function. Therefore, by changing the encryption code by voice, the user can select the communication partner and communicate with the desired partner without any operations. Communication is possible without any operations, so when you need to use both hands to carry luggage, etc.
Not only can it be used when driving a motorcycle to ensure safety by using both hands, but the microphone 3 has a directional feature that captures the user's voice, so it can be used to use audio encryption codes and reduce surrounding noise. As a helmet that can avoid interference and is used by people involved in noisy airports, workers at iron factories, machine shops, construction work, subway construction, etc.
It is possible to provide something suitable for not only ensuring safety but also for business communication. There is no need to attach a radio to a part of the body, and by suppressing the transmission output, it can be operated without a license.
